Double-flowered butterfly pea harvested in September 2025. The eighth photo shows the dried product. The vibrant and stable blue color of butterfly pea has long been used for food coloring. The blue pigment is a unique anthocyanin found in butterfly pea, which changes from pink to reddish-purple when acidic fruit juice is added. We recommend enjoying the color change by mixing butterfly pea syrup with carbonated water and adding lemon juice. Each flower is hand-picked and dried at high temperatures in a food dryer, preserving the beautiful color. For those who are hesitant about imported products, Please try domestically grown, pesticide-free butterfly pea. Recommended storage: Store in a cool, dark place away from moisture. Features: Pesticide-free
